Estate Jewellery by Period: Georgian to Art Deco and After

Why Periods Are Worth Knowing

Period knowledge is not antiquarianism for its own sake. It does three practical jobs.

It lets you date a piece independently of what the seller says, which matters because the vocabulary is loose and "Art Deco style" is not Art Deco.

It tells you what the piece will be like to own — how it is constructed, what its weaknesses are, whether it can be resized, whether the stones can be safely cleaned.

And it points you at where the value is. The market prices fashion, and periods move in and out of fashion. Buying good workmanship from an unfashionable period is one of the few genuinely reliable ways to get more jewellery for your money, and it is why estate pieces do well at auction, as our auction guide sets out.

Georgian, roughly 1714–1837

Georgian jewellery is entirely hand-made, and it looks it. There is no mass production, no standardised finding, and considerable variation between pieces that were nominally the same design.

The defining construction feature is the closed-back setting. Stones sit in a cup rather than open to the light beneath, and behind them is often a coloured metal foil, used to enhance or alter the stone's apparent colour. This is why Georgian pieces must never go near water — moisture behind the foil corrodes it and the stone goes dull or grey, and it cannot be undone without dismantling the setting.

Cutting is pre-industrial. Rose cuts with a flat base and a domed, faceted top are common, as are early cushion-shaped brilliants cut to follow the rough rather than to a formula. These stones do not sparkle the way a modern brilliant does; they glow, and they were designed for candlelight.

Metals are high-karat gold, often 18k or above, and silver used on top of gold for diamond settings because silver was thought to flatter a colourless stone. That silver has usually oxidised to dark grey, which is correct and should not be polished off.

Georgian pieces are genuinely old, often fragile, and command prices reflecting scarcity. They are collector objects more than daily wear.

Victorian, 1837–1901

Sixty-four years is not one style, and the Victorian period divides usefully into three.

Early (roughly to 1860) is romantic and naturalistic — flowers, leaves, serpents, hearts, hair-work, and a great deal of seed pearl and turquoise. Gold is often worked into elaborate repoussé and cannetille filigree, which produces a lot of visual volume from little metal.

Mid (roughly 1860–1885) is the mourning period following Prince Albert's death, and it is dominated by jet, black enamel, onyx and dark, sober designs. Archaeological revival pieces — Etruscan-style granulation, classical motifs — belong here too, following contemporary excavations.

Late (roughly 1885–1901) lightens again. Diamonds become more available following South African discoveries, star and crescent motifs are everywhere, and settings become more delicate.

Construction moves through the period from fully hand-made toward partially machine-assisted. Open-back settings become normal, which means Victorian diamond pieces can generally be cleaned in ways Georgian ones cannot. Gold standards vary widely by country, which is where our international hallmarks guide earns its keep.

Victorian is the period with the widest quality range and, at the lower end, some of the best value in period jewellery — there is a great deal of it, and much of it is out of fashion.

Edwardian and Art Nouveau, roughly 1890–1915

These two run concurrently and look nothing alike.

Edwardian — sometimes called Belle Époque — is the white, lacy, delicate style made possible by platinum. Platinum is strong enough to be drawn very fine while still holding stones securely, and jewellers exploited that to produce garland motifs, milgrain edges, filigree panels and knife-edge wires that look impossibly thin. Diamonds and pearls dominate; colour is used sparingly.

The presence of platinum is itself a dating tool. It was not practically workable in jewellery until the very end of the nineteenth century, so a platinum piece is almost certainly 1900 or later.

Art Nouveau is the opposite instinct: flowing organic lines, insects and dragonflies, female figures with loose hair, and a deliberate preference for materials chosen for beauty over value — horn, glass, enamel, moonstone, opal. Plique-à-jour enamel, which is enamel without a backing so light passes through like a stained-glass window, is the signature technique and is extremely fragile.

Art Nouveau pieces are scarce because the movement was short and the materials were delicate. Good examples are collector items and are priced as such.

Art Deco, roughly 1915–1935

Art Deco is the most consistently fashionable period and therefore the most expensive relative to its material content — and the most faked.

The language is geometric: straight lines, symmetry, stepped forms, strong colour contrast. Platinum continues from the Edwardian period, joined by white gold from the 1920s. Calibré-cut coloured stones — sapphire, onyx, coral, emerald — are cut to fit the setting exactly, which is labour-intensive and a good sign of quality. Baguette and emerald cuts appear alongside old European brilliants.

The transitional cut diamond belongs here, sitting between the old European cut and the modern brilliant, and its presence is a useful date marker.

Because Deco sells, there is a large market in Deco-style pieces made much later, and in genuine Deco pieces that have been heavily restored with modern stones. Two checks help: modern round brilliants in a genuinely period setting are a warning sign, and laser-inscribed stones are unambiguously modern. Our authentication guide covers maker's marks and the paperwork side.

Retro and Mid-Century, roughly 1935–1960

Wartime and post-war constraints pushed jewellery in a different direction. Platinum was diverted to military use, so rose and yellow gold return, often in large, sculptural, three-dimensional forms — big scrolls, ribbons, tank-track bracelets, oversized cocktail rings.

Stones tend to be large and coloured, frequently synthetic ruby and sapphire, which were readily available and were used openly rather than deceptively. Citrine and aquamarine appear in substantial sizes.

Retro is currently one of the better-value periods. The scale suits contemporary taste less than Deco does, so prices lag, while the gold content is often substantial and the workmanship good.

From the 1950s onward, machine production and standardised findings become the norm, and the useful dating evidence shifts from construction to hallmarks and maker's marks.

Buying Estate Sensibly

Judge condition honestly. Look for previous repairs, particularly at ring shanks and clasp joints, where solder of a different colour is usually visible. Check that stones match — replaced stones in period settings are common and frequently modern. Look at wear on the underside of a ring shank; a shank worn thin will need replacing, which is a real cost.

Understand what can and cannot be altered. Many period rings cannot be resized without damaging the design, particularly full eternity bands and rings with stones running around the shank. Our resizing guide covers what is practical.

Buy the piece rather than the period label. "Deco style" is a design description; "circa 1925" is a claim. Ask which is being made.

And use the right channel. Auction is strong for estate work, as is a specialist dealer who will stand behind a date. For contemporary designer pieces at boutique pricing rather than period work, Coutr and Italist are the more direct route, and Ouros Jewels covers coloured-stone pieces in a period-sympathetic idiom.
